Abstract
An embodiment of a method for enabling content personalization for a user based on a cognitive state of the user includes providing an interface configured to enable a third party to request cognitive state data of the user as the user interacts with a content-providing source; establishing bioelectrical contact between a biosignal detector and the user; automatically collecting a dataset from the user; generating a cognitive state metric; receiving a request from the third party for cognitive state data; transmitting the cognitive state data to the third party device; and automatically collecting a dataset from the user as the user engaged tailored content.
Core Innovation
The invention enables content personalization for a set of users based on a cognitive state of the set of users. An interface enables a third party device to request cognitive state data of a user as the user interacts with a content-providing source managed by the third party, and a biosignal detector comprising a set of head-mounted EEG sensors establishes bioelectrical contact with the user and detects EEG signals.
During a first interaction, the method automatically collects a first bioelectrical signal dataset as the user engages content of the content-providing source. A cognitive state metric is generated indicative of the cognitive state associated with brain activity from a plurality of brain lobes, based on the first bioelectrical signal dataset, and in response to a first request from the third party device for cognitive state data comprising the cognitive state metric, the cognitive state data is transmitted to the third party device.
The method generates tailored content for the set of users based on a third party analysis of the cognitive state data. For each user, a second bioelectrical signal dataset is automatically collected during a second interaction as the user engages the tailored content, and tailored content is presented to a second set of users defined by the third party based on the cognitive state metric from each of the first set of users. In an additional aspect, a content stream is collected contemporaneously with the first interaction and the cognitive state metric is associated with the content stream.
Claims Coverage
The provided material includes two independent claims. Across the independent claims, the inventive features number approximately six, including interface-based third-party requests, head-mounted EEG bioelectrical contact and sensing, cognitive state metric generation, transmission of cognitive state data, tailored content generation based on third-party analysis, and content-stream association.
Third-party interface requesting cognitive state data during content interaction
Providing an interface configured to enable a third party device to request cognitive state data of the user as the user interacts with a content-providing source managed by the third party.
Head-mounted EEG biosignal detector with bioelectrical contact
Establishing bioelectrical contact between a biosignal detector and the user, the biosignal detector comprising a set of head-mounted EEG sensors.
Automated EEG dataset collection during first interaction
Automatically collecting, at the biosignal detector, a first bioelectrical signal dataset from the user as the user engages content of the content-providing source in a first interaction.
Cognitive state metric generation from multi-lobe brain activity
Generating a cognitive state metric, indicative of the cognitive state associated with brain activity from a plurality of brain lobes of the user in the first interaction, from the first bioelectrical signal dataset.
Transmission of cognitive state data to third party for analysis and tailored content
Receiving a first request from the third party device for cognitive state data comprising the cognitive state metric; and, in response to receiving the first request, transmitting the cognitive state data to the third party device, generating tailored content based on a third party analysis of the cognitive state data from the set of users.
Contemporaneous content stream association for tailored content
Collecting a content stream contemporaneously with the first interaction and associating the cognitive state metric with the content stream, wherein the content stream comprises a social network content stream; presenting tailored content generated based on the analysis of the cognitive state data, further determined based on the content stream and the association between the cognitive state metric and the content stream.
The independent-claim coverage centers on an interface for third-party requests, head-mounted EEG bioelectrical contact, automatic EEG dataset collection during interactions, generation of a cognitive state metric from brain activity, transmission of cognitive state data to the third party for analysis to generate tailored content, and contemporaneous content-stream collection with association of the cognitive state metric to that content stream.
